To label:
To label the diagram of the antibody.
Introduction:
The structure of the antibody resembles the alphabet Y and consists of 4 proteins (2 light chains and 2 heavy chains).
Pictorial representation:
Figure: The structure of an antibody molecule.
The correct answers are:
- Antigen binding sites
- Light chain
- Heavy chain
V stands for the variable region
C stands for the constant region
Explanation for the answers:
- Antigen binding site − These are the sites on the amino-terminal end of both light and heavy chain. It provides a site of attachment for the antigen.
- Light chain − There is 2 identical light chains consisting of polypeptides. They are bound to the heavy chain via disulfide bonds and non-covalent interactions.
- Heavy chain − There are 5 types of heavy chains (accordingly antibodies are named) and attached to each other via the disulfide bonds.
V stands for variable region. The amino-terminal end of both heavy and light chain of about 100-110 amino acids vary considerably among antibodies and hence are called as variable region.
C stands for the constant region. The carboxy-terminalend of both light and heavy chain shows similarity among antibodies and hence is considered as constant regions.
